Abstract
Embodiments are presented for collaborative device address generation between a wireless client device and a network infrastructure component, such as a wireless access point. The wireless client device and network infrastructure component share information to facilitate collaborative generation of a sequence of device addresses. This shared information includes, in some embodiments, key information and moving factor information. The key information and moving factor information is used to generate a token. A sequence of tokens is generated by updating the moving factor as each token is generated. A corresponding sequence of device addresses are then derived based on the sequence of tokens. Since the wireless client device and the network infrastructure device apply equivalent methods to generate respective sequences of addresses, the network infrastructure is able to efficiently identify a source wireless client device when observing a new device address on a wireless network.
